Ladyhawke by Tom Holt

One of the most popular filksongs of all time is Ladyhawke, which is about a cult film starring Rutger Hauer and Michelle Pfeiffer; if you haven't seen it, it's basically a fantasy story about a knight and his girl who are under a spell cast by a wicked magician; by day, she's turned into a hawk, and by night he turns into a wolf, so they can never meet. Thanks to the help of a little ratlike guy who's a professional thief, they break the spell & live happily ever after etc

Julia Ecklar's song goes -

My jesses are fear and my hood my own lies,
My wings pinned to ground by my theiving.
Each evening I dream that tomorrow I'll rise,
But each dawn breaks, not believing.
I'm a mouse among men with no hopes,no dreams
No notion of right or of wrong;
But a magical maiden more real than she seems
Fills my soul with the glory of song -

Ladyhawke, Ladyhawke, fly bravely on,
Wings spread in each morning's light.
Ladyhawke, Ladyhawke, from dusk to dawn,
Teach me the magic of flight

Now in the UK there's a brand of electric razor specially designed for women and called the Ladyshave. So, inevitably, I wrote -

My motor is fast and my meshes are fine,
For ever I carry on shaving.
Like agonised bee in your bathroom I whine
For the smooth skin you are craving.
Your armpits as furry as lion or bear
I shave till they're perfectly smooth.
From legs I shear off all superfluous hair
And unsightly moustaches remove.

Ladyshave, Ladyshave, drive boldly on,
Mowing through stubble and fur.
Grinding away at the fuzz till it's gone;
Leave me the skin I prefer.

Though swords may be better to hack and to slash
For men like wild beasts to behave with,
They bring out your legs in a horrible rash;
They're a real nuisance to shave with.
And though feminine hygiene, so purists proclaim,
Is no suitable subject for filk,
The Ladyshave's virtues I proudly proclaim,
For they make my skin smoother than silk.

Etc.
